User blog comment:MLGDragon1337/Looking for Perfect IV Ditto on Sp.Defense and Speed/@comment-32085321-20170625142744

If you want a perfect ditto iv on speed and sp.defense, you have to give something that is worth the trade. Even getting a ditto with one perfect iv is rare. In this case quantity is NOT over quality.People will rather keep that one ditto than trade it for 2 other ditto that does not have decent ivs.
